speedtest-cli

The tool provides a command‑line interface that measures internet upload and download bandwidth by communicating with the Speedtest.net service. Users can invoke it directly from a terminal, optionally limiting the test to download or upload only, selecting a specific server, or using a single connection to emulate typical file transfers. Output can be formatted as plain text, CSV, or JSON, and a shareable result image URL can be generated.

It is written in Python and runs on versions 2.4 through 3.7, making it usable on a wide range of systems. Installation is possible via pip, easy_install, or by downloading the script and making it executable. The program supports additional options such as binding to a source IP, setting a timeout, using HTTPS, and disabling pre‑allocation of upload data to avoid memory errors.

The package is intended for developers and system administrators who need a quick, scriptable way to assess network performance without a graphical interface, and it includes a Python API for integration into other tools.
